High-speed grinding is the development trend of today'sChina cut off disc . More and more grinding machine design or grinding requirements are developing at high speed, and the advantages of high-speed grinding; 1. Increased production efficiency, high speed machining speed and low time consumption 2. The surface roughness is reduced, high-speed grinding can improve the grinding frequency, avoiding the insufficient grinding strength of slow grinding and the damage of multiple grinding. 3. The grinding temperature is low, the grinding time of high-speed grinding is short, and the grinding temperature is too late to rise. 3. Make full use of the high hardness and high wear resistance of superabrasives, and the performance is fully utilized. High-speed grinding is not as fast as possible. He has some bottlenecks that limit the speed of grinding. 1. Grinding wheel strength requirements, although the grinding wheel has the characteristics of high strength and high wear resistance, but also requires dynamic balance, otherwise it will cause problems such as cracking of the grinding wheel. 2. Resting technology of super hard grinding wheel. In order to reduce costs, wheel dressing is necessary, but the grinding wheel correction technology affects the speed of high speed grinding. 3. Coolant pressure and nozzle design, the coolant is to avoid workpiece burn caused by instantaneous high temperature. Therefore, a suitable coolant is required, otherwise the processing speed is reduced when the temperature is too high. 4. The rigidity of the main shaft must ensure the rotation accuracy, thermal stability and dynamic balance during high-speed machining.
add to favorites What are the processing methods for ultra-thin grinding discs? Pc  
For the ultra-thin grinding disc with high quality grinding disc factory price, I don't know how much you know. However, it can be confirmed that the grinding disc cutting piece is very helpful to the large machinery industry, such as the cutting of steel pipe. If there is no cutting piece, there is no way to cut it. Therefore, its application There are also many. Ultra-thin cutting blades are also called ultra-thin grinding discs for stainless steel tubes, capillary tubes, glass tubes, quartz tubes, automotive exhaust pipes, brake wires, tungsten wires, molybdenum wires, copper wires and other pipe and filaments. The cutting has a good effect on the cutting of special steel and the slotting of the workpiece. So, what is the processing technology of ultra-thin grinding disc? Below Henan abrasive grinding tools manufacturers come to talk to you. 1. Grinding disc with high quality grinding disc factory price cold pressing process: the bonding agent used is wetting agent and powdery resin. It is usually used as a wetting agent with liquid phenolic resin, furfural, decyl alcohol, cresol, etc. The most used is liquid phenolic resin. 2. The semi-hot pressing process of the grinding disc: the pressing temperature is generally 50-65°C, the viscosity of the liquid resin becomes smaller at this pressing temperature, and the powdery resin can be well integrated, so that the fluidity of the whole resin system is improved. It is easier to fully penetrate the various spaces. Even if the pressure of the press is not too high, it can be molded well, and the holding time does not need to be too long. It is especially suitable for the automatic pressing production line for continuous operation. 3. Grinding disc with high quality grinding disc factory price hot pressing process: mixing requirements are different from cold pressing process. Generally, dry mixing method is used, or 1% of furfural less than the weight of abrasive is used as wetting agent to wet the abrasive, and then mixed with powdered resin evenly. Although the ultra-thin grinding disc is easy to use, we must pay attention to the safe use during the use. For example, when using ultra-thin grinding disc with high quality grinding disc factory price, the operator should wear protective glasses, masks, earplugs, gloves, dustproof clothes. When working on ultra-thin cutting blades, stand on the side of it, and do not operate on the front side, so as to avoid the failure of the cutting disc of the grinding disc to fly out or break out and hurt people. After all, this is working under high-speed rotation.
add to favorites Grinding Wheel Grinding Problem Pc  

In the process of grinding the grinding wheel, the vibration is caused by external disturbance or the unreasonable way of construction feeding, which reduces the quality of the machined workpiece. The problem of grinding the vibration pattern is very common and has been widely criticized in the industry. An in-depth understanding of the causes of the occurrence of vibrating during the grinding process can help companies improve the production efficiency of cut off disc for stainless steel and reduce production costs.

1. Reasons for grinding vibration

When using grinding the cutting disc, according to the characteristics of the vibrating pattern of the observed workpiece, it is found that the fluttering vibration pattern of the grinding surface can be divided into three types: spiral curved shape, linear type and spotted type, wherein the spiral type vibration pattern is trimmed by the grinding wheel and the diamond. The vibration generated between the pens is caused by the poor rigidity of the grinding wheel spindle or by external disturbances: The linear vibration pattern is caused by the imbalance of the grinding wheel, especially in the inner circle grinding. When the grinding wheel is milled or the blockage is uneven and the regeneration effect is also easy to appear linear vibration on the surface. Finally, the spot type vibration pattern is caused by local vibration caused by uneven hardness on the circumferential surface of the grinding wheel.

 2. Impact on the workpiece:

Firstly, the generation of the grinding vibration has a great influence on the life of the workpiece, and the vibration is more likely to cause corrosion. If it is for the bearing, it will mainly affect the accuracy of the workpiece rotation during use. When the vibration is measured, the vibration value is not round enough, and in the case of severe vibration, the vibration of the grinding line is caused.

 3. Solution

When the grinding wheel is finished grinding, the grinding wheel characteristics are selected reasonably (such as uniform hardness, slightly coarser grain size, loose structure); timely replacement of the dressing device of the grinding wheel: often finely dressing the grinding wheel: Balance the grinding wheel to achieve accuracy: Ensure uniform feeding To improve the rigidity of the equipment, the grinding allowance of the blank should not be too large and so on. These precautions can be noticed at ordinary times, which can greatly reduce the occurrence of grinding and vibration problems. Thereby improving the efficiency of processing.

thin flat cutting disc Surface roughness refers to the microscopic geometric features of the machined surface with small spacing and peaks and valleys. It is a collection of microscopic traces left after a large amount of abrasive particles are cut on the surface of the workpiece. The main factors affecting the surface roughness are the characteristics of the working surface of the grinding wheel and the conditions of the grinding motion.

1. The influence of the characteristics of the grinding wheel. For example, the coarser the 7" cut off disc for stainless steel , the smaller the number of sands per unit area of ​​the grinding wheel, the sharper the sand surface of the grinding surface, and the greater the roughness. If the hardness of the grinding wheel is too large, the blunt abrasive particles can not fall off in time, the plastic deformation of the grinding increases, the surface roughness increases, the hardness of the grinding wheel is too soft, the grinding working surface will deform prematurely, and the uneven grinding will make the grinding roughness become larger.

2. The effect of grinding dosage: if the grinding wheel speed is reduced. It reduces the number of abrasive particles involved in grinding per unit time. Then the single abrasive load increases. The plastic deformation of the workpiece is raised, so the surface roughness is increased. If the workpiece speed is increased, the number of grinding abrasive grains in the unit length is reduced. Increasing the grinding thickness and metal cutting amount of the single abrasive grains also increases the surface roughness, and the increase in the grinding depth increases the degree of plastic deformation, thereby increasing the grinding roughness.

In the actual grinding process, there are grinding methods, the number of grinding strokes, the roughness of the previous process, the shape of the cutting edge, the trimming conditions, and the influence of the grinding vibration. For ultra-precision machining, the roughness must be strictly controlled. Impact.

The engine is the heart of the car, and the 4C parts such as cylinder block, cylinder head, crankshaft and camshaft are the core components, and the quality is directly related to the performance of the engine. In the manufacture of 4C parts, problems such as chamber chipping, machining deformation and cutting fluid post-processing costs have always been problems in the manufacture of key engine components.

China cut off disc

New technologies and new technologies such as grinding technology, flexible cleaning technology, simulated cylinder head technology, MQL technology and cluster layout have effectively solved the above problems.
Inverted grinding technology, that is, the grinding wheel spindle is perpendicular to the bottom surface, the workpiece is placed vertically in the machine tool, two grinding wheel spindles drive two CBN grinding wheels to perform vertical grinding from both sides of the workpiece, and the camshaft is processed by inverted grinding to avoid the camshaft In the process of deformation due to self-weight, the workpiece is subjected to force balance, improving product processing accuracy and efficiency.

The inverted grinding technology processing camshaft has the following three advantages:
1. The workpiece is in a vertical state during processing, transforming the gravity of the workpiece that hinders machining in the horizontal machining into a useful top tightening force, avoiding product deformation caused by the gravity of the workpiece itself, and improving the guaranteeing ability of the camshaft grinding precision.
2. The double-grinding spindle is symmetrically distributed with the workpiece as the axis, and the normal forces of the double-grinding spindle cancel each other out, so that the workpiece is radially balanced, and the normal grinding force is balanced by the center frame, thereby realizing the camshaft grinding. The balance of force solves the deformation of the product caused by the grinding force in the camshaft machining.
3CBN efficient grinding technology doubles efficiency. High-strength, long-life CBN grinding wheel is used in grinding, and two CBN grinding wheels work simultaneously during grinding, which greatly improves grinding efficiency.

add to favorites The influence of raw materials on resin grinding wheel Pc  
No Picture

The grinding effect of resin grinding wheel in industrial production is irreplaceable. The resin grinding wheel with good quality has better effect and longer life, and of course it is more favored by users. The quality of the resin grinding wheel is determined by the raw materials for the resin grinding wheel. Good raw materials can produce high performance cutting disc, and vice versa. Let us talk about the importance of raw materials for resin grinding wheels:

      1. Powder phenolic resin. For powdered phenolic resins, fluctuations in flow length, particle size, urotropine content and gelation time can affect the quality of the grinding wheel. The flow of the powder resin is the most important performance index affecting the structure of the binder. The particle size affects the amount of the wetting agent, and the content of the volatiles is also important. In the actual grinding wheel production process, it is necessary to ensure the stability of the performance of each batch of powder resin, so as to ensure the quality of the grinding wheel.

      2. The stability of the technical indicators of the mesh. The mesh was originally applied to the resin wheel and the most important role was to increase the strength of the wheel. As the performance of the resin grinding wheel continues to increase, the role of the mesh in the resin grinding wheel is very important. Mainly manifested in: fluctuations in the strength of the grinding wheel, deformation of the slice, stratification of the grinding plate, and so on. The thickness of the mesh has an influence on the strength and viscosity of the grinding wheel and the cutting and grinding performance of the resin grinding wheel. In theory, under the condition that the grinding wheel production process is stable and allowed, the mesh with the higher amount of glue, the grinding wheel The higher the strength, the better the bonding performance and the more stable the cutting.

      3. Liquid phenolic resin. The fluctuation range of solid content, viscosity, gel time and water solubility of liquid phenolic resin has different degrees of influence. Therefore, the grinding wheel manufacturer must combine its own mixing, forming and hardening process characteristics according to its own product performance requirements. Develop a technical index and range of liquid resins suitable for you.

      The hardness of the resin grinding wheel refers to the difficulty of the abrasive grains on the surface of the grinding wheel falling off under the action of the grinding force. The hardness of the resin grinding wheel is soft, indicating that the abrasive grains of the resin grinding wheel are easily peeled off, and the hardness of the resin grinding wheel is hard, indicating that the abrasive grains are difficult to fall off. The hardness of the resin wheel and the hardness of the abrasive are two different concepts. The same kind of abrasive can be made into resin grinding wheels of different hardness, which is mainly determined by the performance and quantity of the bonding agent and the manufacturing process of the resin grinding wheel. The significant difference between grinding and cutting is that the resin grinding wheel has “self-sharpness”. Choosing the hardness of the resin grinding wheel is actually choosing the self-sharpness of the resin grinding wheel. I hope that the sharp grinding particles should not fall off too early or be blunt. Still not falling off.

While continuing to maintain the rapid growth of the industrial economy, how to reduce or avoid further damage to the environment has become a topic of common concern to the whole society, and green manufacturing has naturally attracted more attention.
The concept of green manufacturing has been proposed for many years. Especially in foreign countries, China cut off disc green manufacturing has been widely regarded as an important means to achieve sustainable development of the manufacturing industry. Some mature green cutting technologies have also been widely promoted and applied.
In China, while manufacturing prosperity has contributed to economic growth, resource waste and environmental pollution have followed, and the consequences have begun to emerge. Now, while continuing to maintain the rapid growth of the industrial economy, how to reduce or avoid further damage to the environment has become a topic of common concern to the whole society. Green manufacturing has naturally attracted more people's attention.
The general trend of energy saving and emission reduction
According to statistics, 70% of environmental pollutants come from manufacturing. While modern manufacturing has brought unprecedented material civilization to mankind, it has also brought more wastes such as waste gas, waste residue and waste liquid to society.
From a certain perspective, the impact of the industrial manufacturing sector under the general trend of energy conservation and emission reduction is obviously the biggest. Such a large pressure is passed on to the industrial manufacturing enterprises themselves, which is unrealistic by simply limiting the number of enterprises and affecting normal production. After all, the goal of achieving energy conservation and emission reduction at the expense of the number and scale of industrial manufacturing companies can only solve the temporary itch and cannot solve the problem fundamentally.
Then to find a solution from the manufacturing process, green cutting technology as a sustainable manufacturing model has become one of the choices of manufacturing companies.
Traditional manufacturing models have a big impact on the environment
The reason why the traditional manufacturing mode can not meet the requirements of energy saving and emission reduction is because the cutting fluid is used in a large amount in the processing process, which brings harm to the environment and the human body itself.
In the field of machining, waste liquids produced using cutting fluids are the main contaminant products. Until now, traditional metal cutting still relies heavily on wet cutting of cutting fluids.
The use of cutting fluid can achieve lubrication, cooling, cleaning, auxiliary chip removal and rust prevention performance, and has a significant effect on improving cutting quality and efficiency, reducing tool wear and the like. The cutting fluid has developed to the present day, and it is widely used in the mechanical processing industry, and it is widely used, and it has become a wide variety of industrial products with a wide range of products.
However, the use of cutting fluids also poses a hazard to the environment and human health. If the waste liquid of the cutting fluid is improperly treated, it will cause serious pollution to water resources, and its biodegradability is poor, and it stays in water and soil for a long time. Even with the strictly treated waste liquid, long-term accumulation can cause pollution, and the toxic chemical components remaining on the chips can also pollute the air.
Oil mist generated during the use of cutting fluid and irritating odors may cause harm to the operator's respiratory system. Long-term exposure to chemicals added to it can cause cancer, so people who have been exposed to poor cutting fluid for a long time are prone to respiratory diseases.
Obviously, the traditional manufacturing mode can not bear the requirements of green environmental protection, and green cutting without using cutting fluid becomes an inevitable choice.

Abrasives are generally sharp, hard materials used to grind softer surfaces. Abrasives are available in two categories: natural abrasives and synthetic abrasives. According to the hardness classification, there are two categories of super hard abrasives and ordinary abrasives. Abrasives range from softer household detergents, gem abrasives to the hardest material diamonds. Abrasives are essential for making every precision product. Many natural abrasives have been replaced by artificial abrasives. In addition to diamond, the performance of natural abrasives is not stable, but it still has its value. Diamond is the hardest abrasive, mainly in South Africa, accounting for 95% of the world's total production, followed by Brazil, Australia, Guyana and Venezuela. Industrial diamonds range from off-white to black.China supply 7" cut off disc After milling, they can be used to make grinding wheels, abrasive belts, polishing wheels and abrasive powders.

Since the 1970s, artificial abrasives have been produced in large quantities, the most important of which are tantalum carbide and alumina. Carbide is commonly known as silicon carbide. It is prepared by mixing pure vermiculite with coke and adding a small amount of wood chips, then placing it in an electric furnace and baking at 2,200-2,480 °C for about 36 hours. Alumina is commonly known as corundum. It is commonly used in the industry to heat and melt aluminum bauxite. It is used as a heat-sensitive metal abrasive in black and white, and it is used to process castings and steel. Synthetic diamond wheels are the hardest abrasives and are necessary for the sharpening of carbide tools. Synthetic diamonds can also be made into tools of various shapes and sizes for cutting glass and ceramics. Boron carbide has a higher hardness than tantalum carbide and is not suitable for making grinding wheels. It can be used to replace expensive diamonds when polishing hard materials. Cubic boron carbide has twice the hardness of tantalum carbide and 2.5 times that of alumina, and it is effective to grind certain tool steels.

One of the important properties of an abrasive is its hardness, which must be harder than the material to be processed. The Mohs hardness tester is commonly used to determine the hardness of various abrasives. Another important property of abrasives is toughness or volume strength. The mixing amount, purity, particle size, and crystal structure of the raw materials can be changed to control this property to suit various applications.

For the manufacture of abrasive products, all raw materials need to be crushed and screened except for powdered talc and iron oxide. The screening particle size should be 4 to 900, that is, the diameter is about 6 mm (millimeter) to 6 μm (1 mm in millimeters). One) or finer. The grinding wheel is the most important abrasive product. It is mixed by abrasive and binder in a certain proportion, sintered by compression molding, and finally must be shaped, balanced and overspeed tested. Abrasive cloth and sandpaper are another kind of abrasive products with a large output. They are bonded to the base material (cloth or paper) by abrasive grains and dried to cut into different specifications. Others are powder or granular abrasives. After screening, they need to be processed by certain processes, such as grinding or polishing abrasives, usually with mineral grease or wax to meet the needs of different working conditions.

1, about the hardware. Why do you mention the hardware first? Because this is the foundation, all the value is ultimately reflected in the output of the device, and all other work is attached to the device. Therefore, the equipment should not be too backward, at least to ensure that the production equipment can produce standard cut off wheel for metal products that meet the technical requirements. In terms of hardware, in addition to production equipment, there are data information collection and processing equipment, which are used after docking with IoT technology. These devices, including sensors, data analyzers, etc., are extremely important and determine whether you are eligible to enter the market on future commercial battlefields.

2, about the software, because the use is not good, many companies do not value, or that did not attract enough attention. In general, many companies don't understand how software can play a huge role, just know that there are benefits, in the context of software promotion, follow the trend. Can you have a role to put aside, anyway, I have it, and there is no obstacle to communicating with customers. Two points have been neglected here. First, the power of software to work is greatly underestimated, especially in the collection and processing of data and information. Second, many companies are only equipped with software, but do not know, software Is a system engineering, how much software can play, depending on the person who uses it, whether the person using it has professional knowledge, systematic training without software, and other aspects of the software in which it is connected Supporting situation, whether the connection with the software is smooth.

3. Regarding management, in some small and medium-sized enterprises, due to the large number of things and relatively few people, the autonomy of each employee is relatively large. Under normal circumstances, the task can be completed according to their own ideas. However, once the company develops to a certain scale, the company begins to improve the system and enter the standardization stage. The company regards the regulatory process as a standard, often resulting in no matter how innovative the employee's ideas are, how efficient it is to solve the problem, but the employees have no right to speak, and the employees are more It is like a tool for performing tasks. Although it does not deny the necessity of regulations and processes, in the process of learning the regulatory process from large enterprises, don't just focus on the form or the essence. The regulatory process ensures that many things are not problematic, but they also rigidify the organization, limiting efficiency and inhibiting the use of employees' intellectual resources. Large companies have the comparative advantage of human resources and market size, so solving the problems he faces, regulations and processes are more important, and his scale advantage can offset some of the inefficient processes. However, the problems faced by SMEs are definitely different from those of large enterprises, and there is no advantage of large enterprises. Under such conditions, it is hard to learn, and the name is advanced, which is obviously tied to his own hands and feet. SMEs have their own advantages, which is more flexible and faster.

The services here arecut off disc for stainless steel actually interoperable, such as abrasives manufacturers or merchants, customers are in arrears, they will provide customers with guidance on template issues, during which time customers need to pay to fulfill their commitments. Conversely, non-interoperable services will gradually undermine the business chain between vendors and customers. More and more, there will be more and more abrasives manufacturers are reluctant to do business in arrears. In recent years, with the rising cost of various materials, warehouse storage, transportation, etc., the abrasives industry has gradually entered the era of low profit, and manufacturers and merchants in the industry are also more cautious about dealing with under-the-counter trading orders. The goods have become the new normal of the abrasives market every day. Since ancient times, although the abrasives market is in arrears with the payment of goods, it is easier to reach orders, and each order is not small, but despite the large amount, there is actually no high profit, meager profit plus the amount (even the last paragraph). The arrears will greatly affect the flow of information of the merchants, which brings great pressure to the merchants! Another important reason is that payments that are often in arrears often become unsuccessful over time or from various external factors. Once a merchant encounters such a transaction, it is a loss-making transaction in a minute. Often, there are people who have lost their money, and finally the capital turnover is weak. One stack is one, the more they are dragged, the more they are overwhelmed until they close their doors. Therefore, with the birth of a new business model, the re-delivery of goods will gradually become a new form of trading in the abrasives market, and the new year will also catalyze the new normality of this pay-as-you-go abrasives market!

During the smelting process, a large amount of soot is generated. In order to facilitate the feeding and dip, most enterprises use semi-closed covers.China cut off disc The problem caused by the semi-closed cover is that the amount of smoke is large, and the second is that the furnace cooling water generates a large amount of steam into the hood. These two problems have brought great difficulties to the purification of flue gas. Many manufacturers have not adopted purification measures, and the pollution is very serious.
1.2 Silicon Carbide Smelting Furnace
The silicon carbide smelting furnace is generally a fixed resistance furnace. During the whole process of smelting, a large amount of dusty flue gas escapes, especially the unloading material is the most serious. Due to the high temperature of the flue gas, the large amount of flue gas, China cut off discthe wide surface of the flue gas, and the high dust resistivity, the purification cost is extremely high, and many manufacturers are discouraged.
1.3 The form of the vacuum hood and the appropriate air intake
Due to the rapid changes in the process equipment of the abrasives industry in recent years, how to design the form of the vacuum hood and select the appropriate suction volume has become a new problem. The dust hood is an important part of the ventilation dust removal system. Its effectiveness greatly affects the technical and economic performance indicators of the whole system, and should be given enough attention.
1.4 Dust removal equipment
The dust removal equipment used in the abrasives industry is mainly bag filter. Due to the misunderstanding of the dust properties or insufficient investment, most of the dust removal equipments are overloaded, with high energy consumption and operating costs.
1.5 Dust removal system wear and tear
The hardness of the abrasive is very high, and the Mohs hardness is above 9.0, which causes the metal components in the cyclone, the air duct, the fan and the bag filter to be seriously worn. 1.6 Investment issues
The ventilation and dust removal project has a high initial investment and high operating costs, and is a high-input and low-output project. Therefore, some manufacturers pay insufficient attention to the work of ventilation and dust removal, and even daunting.
add to favorites Precautions For The Long Life Grinding Wheel Pc  
1. The resin long life grinding wheel must be inspected visually before use. If skin damage is not allowed. 2. The grinder used must have intact guards. The main shaft of the grinder should meet the technical requirements. 3. When the resin long life grinding wheel is installed on the grinder, it is forbidden to beat the grinding wheel. The tightening of the grinding wheel requires moderate tightness. Too loose, too tight or the uneven contact surface between the grinding wheel and the flange is an important factor that causes the grinding wheel to be damaged. 4. Each grinding wheel is marked with a large working speed. It is required that the speed of the resin long life grinding wheel should not exceed the specified safe use speed. 5. Protective equipment (protective glasses, dust masks, safety helmets, protective gloves, etc.) must be worn before using the grinding wheel to ensure safe use. 6. After the long life grinding wheel is installed, it should be idle for 1 minute. Observe the abnormality before using it. 7. When using the resin grinding wheel, it is necessary to slowly enter the knife and operate it evenly. Do not stack the workpieces to prevent the grinding wheel from loosening and falling off, resulting in serious accidents. 8. When grinding and grinding the long life grinding wheel, it should be inclined at an angle of 45 degrees with the object being ground.
add to favorites Hand cone method to test the hardness of the grinding wheel Pc  

The hand cone method was first applied to the hardness test of the grinding wheel in 1926. This method is relatively simple. The inspector uses a steel cone to manually insert the surface of the cut off disc for stainless steel and rotate it. The hardness and hardness of the grinding wheel are judged according to the feeling and the depth of the insertion. This method is completely based on the experience and feeling of the inspector. There is no quantitative data and the precision is low. It is difficult to quantify the graded hardness.

  Similar to this method, there is Japan's Daeue test method, which is applied in Japan, Canada, and Taiwan. The Da Yue test method belongs to the mechanical cone measurement method and is developed on the basis of the hand cone method. This method can also be applied to rough China cut off disc that cannot be measured by sand blasting.

Due to the mechanical structure, the force, the rotation angle and the like are basically stabilized, the measurement reliability is improved, and the measurement result can be quantified, which is a reasonable measurement method. Similar to the hand cone method, there is also a scratch measurement method: this aspect is similar to the definition method of Mohs hardness. In practice, a grinding wheel of known hardness is used to draw another grinding wheel of unknown hardness, according to how much the abrasive falls off. To judge the hard and soft. Japan developed it into a mechanical scratch test method, which can achieve quantitative measurement of the fixed force. The former Soviet abrasive abrasives standard stipulates that the hardness of rubber abrasives is determined by the pressure cone method. In these methods of measuring hardness, the measurement force depends on both the strength of the bonding agent and the toughness of the abrasive, so the measured hardness does not reflect the inherent hardness characteristics of the grinding wheel.

No Picture
The principle of electric spark grinding wheel dressing is in the process of electric spark shaping, standard cut off wheel for metalbecause the second wheel does not touch the tool electrode, the grinding wheel does not It is protected by the repairing force, thus avoiding the occurrence of vibration phenomenon during the shaping of the contact dressing method, so that a higher degree of plasticity can be achieved. And the integrity of the electric grinder sandboxing method is used to make use of the principle of electric machining. The surface appearance of the demon after the grinding wheel is also used. The shape of the wheel surface obtained by his orthopedic method is different. In the electric spark finishing process, the iron-based binder second wheel and the tool electrode valve are generated The spark discharge pulse forms a discharge pit on the surface of the grinding wheel. During the repeated discharge process, the discharge pits overlap each other, and the grinding wheel is gradually repaired. When the single spark discharge energy is appropriate, the higher the frequency of discharge, standard cut off wheel for metalthe better the grinding amount of the grinding wheel. EDM grinding wheel trimming has the following characteristics: 1. It can be in place, online trimming, and ensure grinding precision, easy to operate. 2. Suitable It is used for any grinding wheel with conductive material as the combination of Hu. It is suitable for the dressing of small diameter and very thin grinding wheel. 3. It is convenient and practical. Now it is fast and high-precision trimming of the forming grinding wheel. In addition, compared with other grinding wheel dressing methods, EDM trimming has low cost and is easy to implement. Less process parameters, easy adjustment, etc.
